CHURN.

SPECIFICATION forming part of Letters Patent No. 615,147, dated November29, 1898.

Application filed January 12.1898. Serial No. 666,485. (No model.)

To @ZZ whom it may concern:

Be it known that I, LEROY DRAKE, of Shelton, in the county of Buffaloand State of Nebraska, have invented a new and useful Improvement inAttachments for Revolving Churns, of which the followingisaspecification.

My invention is an improvement in the class of churns whose bodies areadapted to rotate or oscillate, whereby the cream is thrown alternatelyfrom one end to the other and caused to pass intermediately through afixed reticulated diaphragm or partition for the purpose of quicklybreaking the oily globules and inducing separation of the oil or butterfrom other constituents. I have devised an improved attachment for suchchurns which is in the nature of a diaphragm or partition adapted to beeasily and quickly inserted and removed and to be secured in place inthe body of a churn, as hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of abarrel-churn provided with my improved attachment. Fig. 2 is a plan viewof my improved diaphragm or partition.

The barrel A is provided with trunnions a, as required, to adapt it forrotation in a suitable frame. My improved wooden diaphragm or partitionis composed of segmental partsnamely, two semicircular parts B B',detachably connected by means of hooks and eyes b, applied to theirstraight edges.

The part B is provided with a series of openings c, separated byparallel transverse bars d. The other part B is provided with a seriesof holes e. A bar or lever C is loosely hinged at one end f to thecenter of the semicircular part B and is of such length that it extendshalf-way across the other part B, with which it may be detachablyengaged by means of a button D. The latter is pivoted to one of the barsc and is undercut to adapt it to pass over the lever, as shown. The freeend of the lever C rests on a short cross-bar d', which joins two of theaforesaid bars d. The circular edge of the diaphragm is provided withradial points g.

In order to insert and secure the collapsible diaphragm within thechurn-body A, the

lever C is released from the button D, and the two part-s B B areadjusted and held together parallel at an angle to each other. In thisposition the diaphragm is placed in the barrelAand then expanded bybringing the parts B B into parallelism horizontally, in which operationthe points g enter sockets in the sides of the barrel A, and the lever Cis pressed down iiat upon said parts and locked by the button D, asshown. By this means the diaphragm is held iirmly, yet detachably, inthe churn-body A. When the latter is rotated on its trunnions o., thecream is thrown from one end to the other and back again, in whichoperation it passes twice through the openings c and e in the respectiveparts B B', and thereby the oily globules are quickly broken by thenumerous angular edges of the openings as well as by impact on the fiatportions of the diaphragm, so that the cream is quickly converted intoits main constituents, butter and whey. The removable diaphragm is thusa practically important and valuable improvement in churns of the classindicated, and being constructed of wood it may be so cheaply made as tobe an inexpensive attachment.

What I claim is- 1. The improved collapsible diaphragm or partition foruse within a churn of the class indicated, the same comprisingtworeticulated semicircular parts, which are flexibly connected, a lockingbar or lever, and means for securing it in place on the said parts andthereby holding them rigidly in the same plane, substantially as shownand described.

2. The improved collapsible diaphragm or partition for use within achurn of the class indicated, which comprises two reticulatedsemicircular parts iiexibly connected, a lever hinged to one of saidparts, and a device attached to the other part and adapted for lockingengagement with the free end of the lever, substantially as shown anddescribed.

3. The improved collapsible diaphragm or partition for use within achurn of the class indicated, which consists of two fiat semicircularparts having openings and iiexibly connected at their adjacent straightedges, a lever hinged to one of such parts, and a pivoted locking deviceon the opposite parts for IOO 5. The combination with a ehurn-body ofthe diaphragm formed of two hinged foldable parts, and a lever and alooking device applied thereto, said diaphragm being arranged 15 in thechurn-body, as and for the purpose specified.
